How TENS Works

At least two are recognised mechanisms through which the electrical stimulation reduces or eliminates the “pain” symptoms:

1 – The “Gate Control” theory

By means of special adhesive electrodes, the electrical impulses are applied to the skin of the painful area; therefore, through “faster” sensitive nervous fibres, they reach the pain management centres in the spinal cord, and prevent the transmission of pain to the brain.

2 – Hyper-secretion of endorphins

Moreover the electrostimulation stimulate our organism to increase the endorphin production, so raising the threshold of perception of the pain and effectively acting against the chronic pain.

Many people feel immediate benefit from TENS. However a minority may only achieve benefit after repeated treatment sessions and over an extended period of time.
